In an outlying suburb of a medium-sized city, there is a straight residential street lying between two longer, parallel roads. There are a mere 34 houses on the street. Traffic rarely exceeds 30 kilometres per hour.

Despite all of this, a number of deaths and injuries have occurred to people travelling on this street. These deaths and injuries continue against general downward trends in the road toll. Why?

Do the deaths occure to pedestrians? To people in cars? To cyclists? Do victims share a common trait? Like they are only (or in vast majority) children? Women? Do other vehicles, apart cars, bikes, motorcycles and buses use the street? Is there anything besides 34 houses on the street? Any public building? A bus stop?

***** SPOILER *****

The street is Baldwin street in Dunedin, New Zealand, officially recognised as the world's steepest street with a 35% grade.

Dunedin is home to the University of Otago, and is composed largely of students. A number of incidents have occurred in which students have gone from the top of the street to the bottom in a wheeled convenience (such as a shopping cart or a wheeled rubbish bin), similar to riding Niagara falls in a barrel. These have, over the years, resulted in injuries and even deaths. Students being students, injuries and deaths are no deterrent.
